Beit lrnown that I, 'Honden T. Swiisii, a citizen of the United States, and a resident `of Trenton, in the county of Mercer and `State of New Jersey, have invented a certain new and useful Improvement 'in Spreaders, of which the following is a specification.

This invention relates to building` con struction, and more .particularly to anini'- proved device for use in building concrete walls, in order that the same may be made of uniform thickness and thus kept straight and .plumb with the opposite faces thereof parallel vto each other and perpendicular to the base of the wall.

Specifically, it is the object of the invention to ,provide an improved `collapsible extension spreader designed to be placed 'between the panels, or walls of a mold and b-etween which the concrete or cement mixture is to be poured, to subsequently harden, the spreader being' designed to fit between the panels in order -to hold them in uniform spaced Vrelation while at the same ltime being adjustable, `to suit molds of different widths depending upon the thickness of the wall to vbe .produced and being capable of convenaddition to the adjustment or extension thereof to properly engage the inner faces of the walls or sides of the vforni or mold, 'the device serving' to hold the forni in proper rposition and being' easy to remove, whether the wall is reinforced with steel rods orthe ,like or not and the devices being then -repositioned ata higher elevation and the 4form or .mold being1 subsequently taken down after the concrete has-set, the spreaders having` been previously removed. i

Other and further ob'ects of ,my invention .will become readily apparent to r,persons skilled in the art, from va consideration ofA Specficatonof Letters Patent. Patnted Aq1g 22,1922 Application led January 12, 19x21. Serial No. 436,854. Y, i l u vthe followingidescripttion when taken in conjunction with 'the'.A accompanying drawings,

Referring to ,the drawings, yin detail, in which like reference Lcharacters designate corresponding parts throughout the several views, there is shown a cement or concrete wall 10, which may be reinforced or not, 'the saine being poured inthe usual way between the false walls or sides 11 and 1 2 of theusual concrete 7mold or form used in the construc` `tion and erection of concrete buildings of any forni, being of iron, wood or other -Inaterial. lhe collapsible extension .spreader constituting-the subject matter Yof the pres- Yent invention is designedl to be -p'laced'between said walls for the purpose ,of keeping :them uniformly spaced apart, plumb land straight, and with lmuch .less work than 'in connection with the present methods.` Y y y' The device Vconsists of a. 'plurality ofsections 13, 14: and 15, the former sections '13 and 11i being pivotally connected to .form

an art-iculatedsection or member collectively y andthe section 14 thereof being slidab-ly or adjustably connected with the other section 15 and adapted to be held in fixed or rigid relation ,with respectthereto. The section 13 consists of a flat barxof suitable thickness.

having one end directed upwardly as findicated at liand apertured as indicatedja't A17 or otherwise formed for connection with a wire or other cable 18 adaptedto be eXtendl ed over a suitable beam or other part of the wall structure, either permanently or temporarily for the purpose of exerting upward pull thereon by a downward pull on the cable or vwire in the act of collapsing the spreader as will be hereinafter more particularly set forth. The other end of the bar forming the section 13 which may be of metal,

' wood, or other material, though preferably "end of the section 13 is formed withv an end wall 22 extending at right angles to the bar 14 and perpendicular to the top wall 20 so as to engage the inner face of one of the walls of the mold or form. The sec-tion 14 is also preferably of angle iron and the vertical web or flange 23 thereof is rounded olf at the lower corner and outer end, as indicated at 24 and pivotally connected with the vertical web or bar of the section 13 against which it is disposed, as shown at 25, The pivot may be of suitable form and is shown in the form of a headed rivet pivotally connecting the sections to permit relative movement thereof whereby the collapsing function is accom-y plished, facilitated by the rounded portion 24. The end wall 26 of the section 14 produces a shoulder or abutment designed to lengage the shoulder 21 when the sections of the articulated member are disposed vin alignment to render the same rigid, when the upper edge of the bar 13 will be aligned with the upper face of the section 14.

The opposite end of the section 14 is provided in the vertical web thereof with an aperture 27 designed to receive a bolt 28 horizontally therethrough, the threaded shank of the bolt being engaged b-y a winged nut 29 and the head 30 thereof having preferably, a poly sided or polygonal outline, preferably hexagonal and having one corner thereof cut off as shown at 31, to provide a fiat portion for a purpose to be subsequently explained, while the lower portion presents a corner or point 32 adapted to be used as an indicating member in the adjustment of the spreader as will also be explained hereinafter.

The section 15 is also preferably produced of angle iron and the horizontal web 33 narrowed to fit beneath the horizontal web 34 ofthe section 14, while the vertical flange or web 35 of the section 15 is provided with a longitudinal slot 36 parallel to the longitudinal edges of said section and extending substantially throughout the length thereof.

.The walls of the slot 36 are provided at suiting when loosened, to permit longitudinal adjustment of the sections 14 and 15 or eX- tension of the section 15 with respect to 'the section 14 in order to vary the length of the spreader for use with walls of different thicknesses. 1n this position, the flattened portion 31 will seat against the bottom face of the web 33 and the corner or point 32 serves as an indicator to register with a suitable mark or indentation 33 in the inner face of the web 35 beneath the recesses 37 so as to indicate when 'the adjustment has been made to the prescribed or standard size so that uniformity of adjustment in the wall construction is insured. That is, the engagement of the flat portion 31 with the bottoni face of the web 33 prevents turning of the bolt or clamping member so that the point 32 will always be directed downwardly or adjacent to the indentations, while at the same time permitting the nut to be tightened when the sections 14 and 15 are secured in any particular adjustment, according' to the length desired. lt is of course understood that the section 15 will slide with respect to the section 14, the coacting webs preventing the sections from pivoting one with respect to the other and holding` them rigid, in connection with the fact that the aperture 27 is spaced from the inner end ofthe section 14 and thus prevents upward movement of the section 15 on the pivot at that end, by engagement with the end of the web 34, thus preventing the inner ,end of Athe section 15 from swinging downwardly, as it is thought will be clearly understood.

rlhe free end of the bolt shank 23 may be provided with a notch 39 to facilitate the tightening of the nut orretention of the bolt while tightening the nut.

The outer end of the web 33 of the section 15 is enlarged in width relative to the inner portion which is disposed beneath the web 34 and said end is directed upwardly a-s shown at 40 and bifurcated or slotted as indicated at 41 to form a prong or fork, the furcations of which are designed to be straddled by the head of a nail or the like 42 which is driven into the adjacent wall or channel of the mold, in order to secure the spreader in position for use, he vertical web 35 of the section 15 is bent at right an llO gles beneath the end t0 to forman end wall 43 which is designed to engage the wall 12- ythe upper portion of the web 35 at the outer end thereof, and the lower end is disposed to project in the plane of the web 35 lengthwise of the spreader or sections thereof and is tapered `to produce aspur ist which is forced into the wall of the mold to initially hold lthe same and cooperate with the nail or other fastening means 42 above referred to in retaining the device in position. i i

1n use, the device is applied as just described', the articulated member being in a collapsed position or open with the section 13 swung on the pivot 25 of the section lf-i te the position shown in dotted lines in Figure 1 of the drawings. The device having been disposed between the walls or" the niold above the cement or base of the wall, the section 'l-3 at the inner 'end thereof is pressed downwardly so that the device will be in an ei;-

ktended position, adjustment having been previously accomplished to malte the spreader of the required length. ln this fashion, the end wall QQ will be brought into engagement with the other wall of the mold, being shown engaged with the walls 11 and 12 in the construction illustrated, and the sections 13 and 14 will be disposed in alignment, thus producing a rigidv brace between the walls of the mold, so that the latter will be held uniformly spaced apart and thereby insure uniformity in the thickness of the walls, thus produced. 1n this way, the 'building of concrete structures or walls will be greatly facilitated and the saine will be lrept 'plumb and straight, the faces thereof being parallel or otherwise related as desired.

1t is of course to be understood that when the cement is poured to a height adjacent to the spreader, the latter is removed and reapplied, any number of the devices being` einitself to those skilled in the art 1What is claimed `is l.
